Laboratory, will create a one-to-10 billion scale model of our solar system.

 Urquhart, who worked at the National Aeronautics and Space Administration’s Jet Propulsion Laboratory and Ames Research Center before joining the Science/Mathematics Education Department at UTD, will conduct hands-on activities to aid in understanding scale in the solar system, including the creation of a one-to-10-billion scale model of the planets and sun using everyday materials. The lecture, which is free and open to the public, will begin at 6 p.m. in the Conference Center, Room 1.112.

 The fifth and final installment in the UTD seminar series will be a presentation on April 11 by Nobel laureate and visiting UTD professor Dr. Russell Hulse. In his talk, “Science, from Nobel to Neighborhoods,” Hulse will explain how the experience of winning the Nobel Prize led him to a new focus on bringing the excitement and adventure of science to new generations of students and adults through community-based science education.
